Soundpainting is a universal multi-disciplinary live-composing sign language for every kind of artist (musicians, actors, dancers, visual artists), and is still evolving since its creation in 1974 by Walter Thompson in Woodstock, New York. Soundpainting gives to the soundpainter (the composer) the possibility to compose multi-disciplinary creations in real time by signing gestures (more than 1500 different signs in 2023) to indicate the material the performers will realize and the soundpainter will shape into the composition.[1]
